ICF Construction for Homes and Additions

ICF construction

Insulated concrete form foundations, walls and complete homes: stronger, quieter and far more energy efficient than a standard framed wall, built by our own crews.

ICF construction · Woodstock, Kitchener-Waterloo & Southwestern Ontario

Why Build With ICF?

Insulated concrete forms are stacked foam blocks that are reinforced with steel and filled with concrete. The result is a solid, continuous wall with built-in insulation on both sides: no thermal bridging, no drafts, almost no outside noise, and a structure that shrugs off wind, fire and pests. JKF builds ICF foundations, above-grade walls and complete homes, then finishes them with our own carpenters and masons.

What we build

ICF foundations for new homes and additions, full-height ICF walls, walk-out basements, garages, and complete custom homes. We also build traditionally framed homes when that is the better fit.

What it means for you

An ICF home typically cuts heating and cooling costs substantially, stays quiet next to a busy road, and has a basement that feels like the rest of the house. Insurance and resale value benefit from the solid construction.

  • Lower heating and cooling bills
  • Quiet, draft-free rooms
  • Dry, comfortable basements
  • Stronger structure with a longer lifespan
Modern rural home with stone facade, dark siding, and detached outbuilding

Why build with JKF

We are a general contractor with our own carpentry, masonry and flooring crews, so the same company that pours your ICF walls frames the roof, lays the stone and finishes the interior.

  • Foundation to finishing by one company
  • Red Seal carpenters and masons
  • Drawings, engineering and permits coordinated
  • Fully insured, WSIB covered

Who runs your project

Meet the Person Running Your Project

Jesse was born into the trades. He worked for his father's company, J&J Masonry, from a young age, completed a Red Seal masonry apprenticeship and spent years on the tools as a stone mason before taking ownership when his father retired. Over the next decade he built the team that is now JKF Custom Construction, bringing Arrow Hardwood & Laminates and Decked Out Carpentry into the company. He leads a hand-picked team of tradespeople who treat every project like their own home.
